The cell notation for the given voltaic cell is
SO₂(g) | SO₄²⁻(aq) || Cu²⁺(aq) | Cu (s)
What is a voltaic cell?
A voltaic cell often called a galvanic cell, is a type of electrochemical cell.
It is a combination of two metal rods called electrodes.
A half cell is formed when both electrodes are submerged in a solution containing a particular mix of ions.
The electrolyte is the liquid in which both electrodes are submerged and acts as a salt bridge connecting the half cells.
The cell undergoes a chemical reaction known as a redox reaction.
One of the electrodes serves as an anode and undergoes oxidation, while the other electrode serves as a cathode and undergoes reduction.
To write the cell notation, write the half-reaction of the cells.
At the anode, oxidation occurs
[tex]SO_2(g) \longrightarrow SO_4^{2-}(aq) + 4H^+ (aq) + 2e^-[/tex]
At cathode
[tex]Cu^{2+}(aq) + 2e^- \longrightarrow Cu(s)[/tex]
In the cell notation, the anode is written on the left side, and the cathode is written on the right side. A vertical line differentiates the phases and the double vertical line represents the salt bridge.
